Changing Ideas About Space
Science · Space Exploration · conceptual
Understand that ideas about the solar system changed over time: ancient people believed Earth was at the centre (geocentric model, Ptolemy), until Copernicus proposed the Sun was at the centre (heliocentric model), later confirmed by Galileo’s telescope observations
What mastery looks like
- Describe the geocentric model (Earth at the centre) and name Ptolemy as its main proponent
- Describe the heliocentric model (Sun at the centre) and name Copernicus as the person who proposed it
- Explain that Galileo used a telescope to find evidence supporting the heliocentric model (e.g. moons orbiting Jupiter)
Check your understanding
Can Changing Ideas About Space tell you that people used to think the Sun went around the Earth, and explain how scientists like Copernicus and Galileo changed our understanding?
